Apple's new App Clips feature will let you use a tiny slice of an app when you need it, without making you install it first.

For example, you'll be able to place widgets on your homescreen, and there's a new app drawer and new privacy controls. .

With an App Clip, however, you'd only need to scan a QR Code or tap your phone against an NFC tag on the scooter you want to rent, for example, to display a small card on your iPhone. .

App Clips will use any debit or credit cards you've added to Apple Pay. 

Apple also created specialized App Clip codes that let you know it'll add the miniaturized version of the app if you scan it. 

Once a Clip is added to your phone, you won't have to add it to your iPhone the next time you want to use it, unless, of course, you deleted it after you were done. 

App Clip codes are going to be everywhere soon. 

App Clips won't clutter up your homescreen as regular app icons do

Maybe you'll be able to use App Clips to find out which song is playing, try out a new photo filter or to upload a quick video to a social network
